Looking for scenes with couples arguing, or one of them (preferably girl) feeling betrayed/having a sad or vulnerable look on. Also scenes with one of them walking away from the other, such as the ending of 50 CM per second. As well as scenes with the girl holding onto the guy, also a scene from 50 CM per second when she holds onto the guy's coat and a tear drops on her hand.

All of these are harem shows that have at least 1 girl who gets dumped and just starts crying (in the rain) but they all have several girls that do different things so you should be able to find all of the scenes you need between all of them
